To all whom, it may concern:

Be it known that I, AUGUs'rIN MARION BEN- EDIG, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Adding-Machines; and I do hereby declare the following tobea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in adding-machines, and particularly to a mechanism for indicating a particular sum to be added or a sum obtained by the addition of two or more numbers.

The object of the invention is to provide a simple, efficient, and practical mechanism for the purpose of indicating a particular numher by means of one or more dials which are provided with numerals spaced upon their upper surfaces.

Another object of the invention is to prov ide rotary indicating means cooperating with lever means for operating and controlling the movement of auxiliary indicating means.

Another object of the invention is to provide a frame. or casing with indicating means and to construct upon the base of the frame a perpetual calendar.

A still further object of the invention is to provide a plurality of dials, each dial indicating different numerical values, and means for positioning said dial for the purpose of exhibiting certain numerals formed upon the dials in predetermined positions.

With these and other objects in view the invention consists in certain novel constructions, combinations, and arrangements of parts, as'will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed outin the claims hereto appended.

In the drawings, Figurel is a fragmentary plan view of a completed mechanism constructed in accordance with the present invention. Fig. 2 is a fragmentary plan view of the base of the casing or frame, showing the ratchet-wheels and ooacting lever mechanism in an assembled position therewith. Fig. 3 is a transverse sectional view of the mechanism, taken on lines 3 3, Fig. 1. Fig. 4 is a perspective view of a stationary dial which is secured to or formed integral with the frame or casing of the mechanism. Fig. 5 is a perspective view of the lever mechanism which is assembled with each of the dial structures. Fig. 6 is an inverted fragmentary plan view of the base of the frame or casing of the mechanism, showing the perpetual calendar formed thereon.

In carrying out the present invention I cmploy a plurality of dial mechanisms, each succeeding dial mechanism indicating the value of the next highest order of the numerical denomination as, for instance, the dial mechanism 4 indicates units, 5 indicates tens, 6 hundreds, and subsequently the other dials employed in the construction of a completed mechanism indicate the next highest orderin the numerical denomination increased by ten.

I will specifically describe the construction of one of the dialmechanisms, and preferably that designated by units, as it will be obvious upon considering the drawings that the construction is similar in each of the succeeding dial mechanisms as that depicted in the drawings for mechanism 4:.

A casing or frame 7, preferably rectangular in construction, is provided with cutting edges 8 8, which are formed for the purpose of employing said casing or frame as a papercutter in addition to a paper-weight. If it is desired, a scale, as 9, may be formed upon one or both of the edges 8 8 for employing the same as a rule. The casing7 is provided with a cover 10, which is removably mounted upon the same. Referring to the dial mechanisms, and preferably that designated as units, the vertical shaft 11 is provided with an integral rotatable dial 12, which is preferably secured upon one end of said shaft 11 and outside of cover 10. The shaft 11 is journaled in a suitable aperture formed in the cover 10 and in a journal-box 11 or the like formed in the upper surface of the base of easing 7. A ratchet mechanism is secured to the shaft 11 of each dial mechanism. Each ratchet mechanism comprises a ratchet-wheel 12, which is provided with ten teeth, and above said ratchet-wheel and secured to shaft 11 is a cam member 13, which is provided with a single tooth. The body portion of the cam member is disk-shaped in form, and the single tooth projects therefrom. Secured to the upper surface of the base and contiguous of the members 12 and 13 is a rectangular guide 14. Slidably mounted upon the guide 14 is a lever mechanism 15. Lever mechanism 15 comprises in its construction an approximately rectangular frame 15, which is provided with an elongated central aperture, which is adapted to permit of said mechanism being positioned upon the stationary lug or guiding member 142 for the purpose of permitting of slidable movement of the same upon the base of the casing 7. The member 15 is also provided with a right-angle extension 16, which is bent upwardly and outwardly for the purpose of permitting of said tooth or extension 16 to engage the cam member 13. Pivotally secured to the frame or member 15' and near one end thereof at 17 is a lever member 18. The lever member 18 comprises in its construction a body portion which is bent intermediate its length at 19for the purpose of permitting of the hooked end 20 to rest upon the base of frame or casing 7 and normally in engagement with the toothed ratchet-wheel 12. Integrally secured to lever member 18 and extending at right angles therefrom is an arm or extension 21. In Fig. 5 of the drawings said arm 21 is provided with a pin 22, upon which the spring 23 is adapted to be mounted. In Fig. 2 the extension or arm 21 is apertured near its outer end for the purpose of receiving one end of the spring 23 instead of having said pin attached to a pin 22, as depicted in Fig. 5. The opposite end of spring 23 is secured by any suitable means to the base of frame 7. Owing to the construction of lever 18, it will be obvious that the member 15 is permitted to be secured directly against the base of the frame,

while the lever 18 is secured upon the upper surface of frame 15', both of which arepermitted to move independently of each other. To prevent shafts 11 from rotating in one direction, thereby preventing movement of the ratchet-wheels, each dial mechanism is provided with a dog 24, which is normally held in engagement with the ten toothed wheel 12 by means of a spring 25.

A plurality of keys 25 are positioned upon and near the edge of dial 12". The keys 26 are preferably ten in number, and each of said keys is positioned contiguous to unmerals formed upon the upper face of dial or disk 12*, said numerals being 1 to 0, respectively. The keys 26 are preferably spaced a suitable distance above dial 12. Dial 27 is secured by means of an integral indicatingplate 28, which is provided with a right-angled extension 29 to one side of easing 7. If it is desired, the arched indicating-plate 28 may be integrally secured to one side of casing 7. Upon the under side of stationary dial 27 a suitable recess 30 is formed for the purpose of permitting of an integral projection extending from dial 12 to engage said recessed portion 30. The purpose of this recessed portion of dial 27 is to positively retain shaft ll in a vertical plane, and thereby assuring of the rigidity of the ratchet-wheel and cam member when mounted upon shaft 11 for normally retaining the same in engagement with the frame 15 and lever 18. An aperture 31 is formed upon stationary dial adjacent to the arched portion 28 for the purpose of permitting of the exposure of the numerals which are formed upon revoluble dial 12. The arched portion 28 may be used to indicate the numerical value of the dial mechanism.

It will be obvious upon referring to the drawings, Fig. 1, that dial mechanism 1 is designated by units, which are formed upon the upper surface of member 28. The subsequent dial mechanisms and the coacting parts are designated upon members 28 by tens, hundreds, &c.

Upon the rotation of dial 12 it will be apparent that the numerals, which are formed upon the upper surface thereof, will be exposed to view through apertured portion 31 of stationary dial 27. Upon stationary dial 27 there are formed numerals from 1 to 0, respectively.

Upon the bottom of the casing 7 I have arranged a perpetual calendar which comprises in its construction a sheet of material 32, upon which is printed the months of the year, together with the dates for indicating the days contained in each month. An endless ribbon 33 is mounted upon casing 7 and is adapted to be positioned between the months of the year and the dates formed upon the sheet 32. The purpose of this ribbon upon which the days of the weeks are designated is to indicate the days of the week in each month and the dates thereof. The ribbon 33 is mounted within a slot 34:, which is formed upon the bottom of easing 7. The sheet 32 is preferably constructed of transparent material--celluloid, for instancefor the purpose of permitting of the letters or characters upon the ribbon 33 to be easily discernible. A plurality-of brackets 35 are positioned upon one side of easing 7 and within the same. Journaled upon an extension of bracket 35 are rollers 36, over which ribbon or sheet is adapted to be passed when it is desired to position the same for the purpose as is hereinafter specified. \Vhen it is desired to move the ribbon, this can be accomplished by engaging the same at 37 by means of any suitable instrument which will permit of the actuation of the same. Upon the ribbon 33are letters designating the days of the week. Said letters are adapted to be positioned contiguous to the numerals representing the dates of the days in each week of each month. As an illustration of the purposes of this construction and arrangement it will be apparent that in designating the first day of the year, if the same should come on Friday, it will be necessary to move the ribbon so as to place the letter F in parallel position with the numeral 1 appearing in January. The subsequent day of the week, as Saturday, will occur upon the second, and the remaining days of the month will be properly designated by the numerals indicating the dates. When it is necessary to position the ribbon after the first positioning at the beginning of each year, as in the case of leap-year, this can be easily accomplished by causing sliding movement of the same at 37 by means of any suitable instrument. calendar in combination with the other mechanisms of this invention is to provide a simple and convenient construction for the purpose of assisting in the computing of interests in relation to commercial papers, or, as will be obvious, the calendar will provide a ready reference for any other purposes when it is desired to ascertain the date of a particular day.

The operation of the mechanism is as follows: W'hen the dial mechanisms are in the position depicted in Fig. 1, the character O,formed upon the revoluble dials 12, will be exposed to view through the openings 31 of the stationary dials 27. If it is desired to expose a character other than 0 through the opening 31 of the stationary dial in the units mechanism, this may be accomplished by turning the revoluble dial preferably from right to left, as illustrated by the arrow, Fig. 2. Upon each complete revolution of dial 12 the extension of cam member 13 will engage the-lateral extension 16 of the frame 15 and will impart longitudinal movement to all of the lever mechanisms when positioned as shown in Fig. 2. After the cam in any of the dial mechanisms has actuated the lever mechanism of the respective dial mechanisms spring 23 will return said lever mechanism bodily longitudinally to its normal position, so as to place the extension 16 of the frame 15 in the path of movement of the extension of cam member 13. In all of the dial mechanisms except the units mechanism the levers 18 will be retained by means of the springs 23 in engagement with the ratchet-wheels 12.

While I have described in the foregoing description the peculiar construction of the dial mechanisms which are employed in the present invention and also the cooperating elements employed in the construction of a complete machine, it will be obvious to one versed in the art to which this invention relates that deviations may be made in the manufacture of devices constructed according to the present invention, and I therefore reserve the right to make such alterations, modifications, and changes as shall fairly fall within the spirit and scope of the present invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
